I’m attempting to set up Manual Port Forwarding to stabilize a server that has had issues staying accessible remotely. I have a static IP properly assigned thought my router however, when I go to set a port to forward my server will only work if I set 32400. Any other port in the range the 20,000 to 50,000 range on the Plex help page will not work.
I would normally just pick 32400 and call it a day, however I have a 2nd server on the network that I currently running on that port so an additional port is required. I can toggle back 32400 back and fort between each server and it runs properly. I just can’t get either of them to accept a different port.Has anyone encountered this issue and/or have any insight? Thanks!
WAN/External Port: Port 32400 (TCP) is default, but you can generally use any available port in the 20,000 to 50,000 range.
LAN/Internal Port: This will always be 32400.
So you can use any external port (as long as it matches the port you’ve specified in your Plex server setup) though you’ll need to forward that external port to a 32400 internal port, there’s no way around it.
@Dingmatt I understand that the support pages claims any port in that range will work, but that’s not what I’m experiencing. I’ve specified dozens of ports, in 20,000 to 50,000 range, for my router (already set with static IP address for Plex server), specified the corresponding port in my server setting, and of every port I’ve tried ONLY 32400 will work.
Long short, everything properly set and matching in router and server. Only 32400 works!
@hf995 so you’ve tried dozens of external port numbers but kept the internal port to 32400? If so then I don’t have any idea, it works fine on my setup so I’m thinking maybe firewall?
@hf995 What router do you have that you are trying to set this up in? Also, on the Settings page under the Server section on the Remote Access tab, you have the Manually specify public port checkbox checked and your new port that you want to use entered in there, correct? And then after you hit Apply you are getting the red X and that your server is not accessible?
If you can give the make and model of your router it would be easier to look into and make sure you are setting it up correctly in there. Like Dingmatt, I have manual port forwarding setup and it is working fine.
@shark2k sadly I’m stuck using the Verizon Fios supplied modem router combo “Fios Quantum Gateway G1100” to avoid a Double NAT situation.
I have the local IP address of my server set as static through my router and, as you describe above, I input the forwarded port in “manually specify port forwarding” of server setting, check the box, and then repeatedly, hit “apply.” Each time, I get the red X.
I mean no offense by this, it’s just hard to establish clarity on both ends of text conversations. But, just to be clear, you are entering 2 ports into your port forwarding rule right? The external port that you choose, and the internal or “forwarded to” port that has to be 32400.
IIRC, on fios gateways there is an “Advanced” button you have to click to get the second internal/destination port entry. The default is same as the forwarded port, this must be changed to 32400.
@tobytl no offence taken. I’m a novice here trying to wrap my head around this. I did not realize about the additional layer of setting in the fios gateway. Now I see… Below is a screenshot of the advanced setting with all the options set to “specify.” Can you lend any direction on how what does where to forward an external port other then 32400:
